Abstract

Neutron-rich ^34,35Al isotopes have been studied through Coulomb excitation using LAND-FRS setup at GSI, Darmstadt. The method of invariant mass analysis has been used to reconstruct the excitation energy of the nucleus prior to decay. Comparison of experimental CD cross-section with direct breakup model calculation with neutron in p_3/2 orbital favours ³⁴Al(g.s)⊗ν_p3/2 as ground state configuration of ³⁵Al. But ground state configuration of ³⁴Al is complicated as evident from γ-ray spectra of ³³Al after Coulomb breakup of ³⁴Al.
